It's only tricky if you never mastered it, personally I always enjoyed a big Pyro job on the smaller stuff I could do up to 8 terms an hour

Alas, time is money on most jobs and skilled sparks like yourself are harder to come by. At least, cheaply...

I think pyro is brilliant stuff, most installations will outlive the building's use. In fact, I expect 100 year post-nuclear-apocalypse there would still be MICC circuits that would pass an inspection!

I did a pyro job in an office block 39 years ago, new build did all the staircase lighting and fire alarm system.
That was in Barnet London, when I visit my mother (in Barnet) I still pass the block, when the lights are burning on the staircase I chuckle an think I did that still going strong. lol
